Document Summary
May 11/2017: scientific practice (empirical, systematic knowledge-building) isn"t confined to one. Three points tradition: unifying similarities can be missed, context of the scientist influences how they do science, a form of farming, possibly 2000+ years old, helped support large populations, recently discovered by archaeologists. Evolutionary nuts & bolts: cells, dna & heredity. How do you transfer traits between generations? (remember scientific explanations are proximate & mechanistic) Change in trait frequencies from generation to generation. That process (in sexual organisms) depends on: Heredity: the passing of biological characteristics from one generation to the next. Dna: deoxyribonucleic acid the molecular basis of genetic inheritance. The genetic code: a g c t. It"s a think about how much information binary stores (not binary) code. Every cell has 23 x 2 = 46. All your chromosomes make up your karyotype. Gene: a segment of dna with an identified function (usually codes for a protein).
